Overview

The LMK5B33414 is a high-performance network synchronizer and jitter cleaner designed to meet the stringent requirements of ethernet-based networking applications with < 5-ns timing accuracy (class D). The network synchronizer integrates three DPLLs to provide hitless switching and jitter attenuation with.

  • Ultra-low jitter BAW VCO based Ethernet clocks - 42-fs typical/ 60-fs maximum RMS jitter at 312.5 MHz - 47-fs typical/ 65-fs maximum RMS jitter at 156.25 MHz
  • 3 high-performance Digital Phase Locked Loops (DPLLs) with paired Analog Phase Locked Loops (APLLs) - Programmable DPLL loop bandwidth from 1 mHz to 4 kHz - < 1-ppt DCO frequency adjustment step size
  • 4 differential or single-ended DPLL inputs - 1-Hz (1-PPS) to 800-MHz input frequency - Digital holdover and hitless switching
  • 14 differential outputs with programmable HSDS/ LVPECL, LVDS and HSCL output formats - Up to 18 total frequency outputs when configured with 6 LVCMOS frequency outputs on OUT0_P/N, OUT1_P/N, GPIO1 and GPIO2 and 12 differential outputs - 1-Hz (1-PPS) to 1250-MHz output frequency with programmable swing and common mode - PCIe Gen 1 to 6 compliant
  • I2C or 3-wire/4-wire SPI interface
